RUDOLF SGHLIEPER, OF REMSCHEID-HASTEN, GERMANY HYDRAULIC DRIVEN WASHINGAPPARATUS Application filed December 23, 1929, Serial No. 416,094, andin Germany May 3, 1929.

Cleaning apparatus for cars are known, in which a sponge acting with itsfront surface is rotated by a hydraulic engine.

The known apparatus present the disadvantage that, the rotated sponge,owing to the centrifugal force produced, throws off to all sides thewater fed thereto thereby wetting and dirtying the user of theapparatus, andsurroundings near the object which is being cleaned.

The device according to the invention differs from the knownarrangements of this kind in that the sponge, driven by the hydraulicengine, is surrounded by an annular sponge, rigidly connected with thecasing of the driving engine. Further an inclined trough is provided inthe casing, serving for guiding the driving water from the blades of thewater wheel of the engine to the openings in the sponge. v

The important advantages obtained by the invention are that the waterthrown off by the sponge set in rotation is caught by the stationaryannular sponge surrounding the former, that the driving water is fedmore accurately, owing to the gutter leading from the engine bladestothe sponge and is supplied directly onto the surface to be cleanedthrough openings in the sponge.

An embodiment of the invention is illustrated by way of example in theaccompanying drawing in which:

Fig. 1 shows the apparatus in inverted position partly in section online AA of Fig. 2 and partly in elevation.

Fig. 2 is a top plan view, the driving mechanism being shown partlyexposed and the water injecting device in section.

A cross piece 0 is fastened in a casing a which has a collar 72 forminga shoulder. In this cross piece 0, on the one hand, an axle e of a waterwheel f is rotatably mounted on a centre point d and, on the other hand,an axle g of a spur wheel h is fastened which meshes with a pinion i ofthe water wheel axle e. A bearing disc is screwed onto the boss h of thespur wheel 70 carries a sponge Z. Driving water is supplied in knownmanner to the water wheel f by means of an injecting nozzle m, forming ahandle n, fastened on the circumference of the casing a and connected tothe water main by means of a hose. The driving water sets the waterwheel f and therefore the pinion i, spur wheel h, bearing disc 70 andwith same sponge Z in rotation and passes from the blades f. of thewheel f into an inclined gutter 0 from which it flows onto the sponge Zand through openings p in the sponge onto the surfaces to be cleaned.The water thrown out tangentially by centrifugal force from the sponge Zis caught by an annular sponge Z surrounding the sponge Z and fastenedto the collar Z) of the casing a.

I claim:

A hydraulic driven washing apparatus,

comprising in combination a rotary sponge having passage anddistributing apertures for the washing water situated away from thecentre of rotation of said sponge, a casing carrying said rotary sponge,an annular stationary sponge surrounding said rotary sponge, adapted tocompletely catch the water thrown off by said rotary sponge, and aninclined trough in said casing adapted to supply the washing water tothe apertures of said rotary sponge means for rotating said rotarysponge accommodated in said casing. v

In testimony whereof I affix my signature.
